UM_6613_045 78M6613 Evaluation Board User Manual 1 Introduction The Teridian™ 78M6613 Evaluation Board is an electrical measurement unit for performing measurements of up to two single-phase AC loads. It incorporates the 78M6613 power- and energymeasurement IC and connects to a PC through a USB cable such as the one provided in the demo kit. The Evaluation Board demonstrates the capability of the 78M6613 energy-meter controller chip for measurement accuracy and overall system use.
78M6613 Evaluation Board User Manual UM_6613_045 1.3 Safety and ESD Notes EXERCISE CAUTION WHEN LIVE AC VOLTAGES ARE PRESENT! Standard ESD precautions must be taken when handling electronic equipment. The 78M6613 contains ESD protected interfaces. Do not connect test equipment, ICE emulators or external development boards directly to the 78M6613 hardware. Damage to the 78M6613 and external equipment will occur due to the 78M6613’s “high side” reference topology. The 78M6613’s V3P3 (i.e.
UM_6613_045 78M6613 Evaluation Board User Manual 2 Installation 2.1 USB Driver Installation This evaluation kit includes an isolated USB interface for serial communications with a PC. The FTDI USB controller IC FT232R performs the USB functions. The FTDI driver for Windows presents a virtual COM port for enabling serial communications. Control of the 78M6613 Evaluation Board can be managed using a terminal emulation program. The FTDI Windows driver is a certified driver for Windows 2000 and Windows XP. 1.

UM_6613_045 78M6613 Evaluation Board User Manual 2.4 Verify Serial Connection to the PC After connecting the USB cable from the 78M6613 Evaluation Board to the host PC, start the HyperTerminal application (or another suitable communication program) and create a session using the communication parameters shown in Table 1.
78M6613 Evaluation Board User Manual UM_6613_045 Note that port parameters can only be adjusted when the connection is not active. It may be necessary to click the Disconnect Button to disconnect the port. FTDI COM Port Trouble-Shooting If the FTDI device driver did not install properly, there would be no assigned COM port number for the FTDI controller. Repeat the USB Driver Installation, see Section 2.1. Microsoft Windows may associate a Ball Point device to the FTDI USB controller.
